Title: Improvements in or relating to surgical implants
IPC: A61L27/48
Filed: 1962-03-01
Abstract: A fabric of material non-absorbable in the body e.g. 'Teflon', 'Dacron', 'Vinyar', 'Orlon', (Registered Trade Marks) cotton or silk is incorporated with collagen fibrids to form a fabric for use in prosthetic surgery (see Division A5).  The fabric may be woven, crocheted, knitted or braided to form a film, tube or y-tube, the collagen fibrids being deposited on both sides of the fabric, the interstices of which are sufficiently open to permit the fibrids to extend through them.  A multifilament strand of the non-absorbable material may be woven with a multifilament strand of collagen to form the fabric.ALSO:A surgical prosthesis or prosthetic material comprises a fabric which is non-absorbable in body fluids and in which collagen fibrils are incorporated.  The non-absorbable fabric or filaments comprise synthetic fibres e.g. "Teflon," "Vinyon, "Dacron" or "Orlon" (Registered Trade Marks) or cotton or silk.  A dispersion of collagen fibrils is applied to the non-absorbable fabric in a tray and after freezing is dehydrated with isopropanol to which is added sufficient ammonium hydroxide to neutralize the acid. The fabric thus coated on both sides with collapen fibrils is squeezed and dried by heat.  Alternatively, the dispersion of swollen collagen fibrils is passed through a spinnerette into an acetone dehydrating bath and then dried to form a multifilament collagen strand which is woven, knitted, braided or crocheted with filaments, which are non-absorbable in the body, to form a fabric.  The collagen dispersion may be introduced into a glass tube along the axis of which is a glass rod covered with rubber sleeve, a prefabricated tube of non-absorbable fabric being spaced from the rubber sleeve so that it becomes coated with the dispersion on both sides.  After freezing and dehydrating, the coated fabric tube is withdrawn from the glass tube and is used as a prosthetic replacement of a body passage e.g. an artery.  In fabric tube may be reinforced with rings or a helix made of "Teflon" before coating with collagen fibrils.

Title: A new or improved means for ensuring that aircraft controls are unlocked before the aircraft takes off
IPC: B64C13/30
Filed: 1943-05-29
Abstract: 566,583. Controlling aircraft. SHORT BROS. (ROCHESTER & BEDFORD), Ltd., and JONES, E. May 29, 1943, No. 8606. [Class 4] [Also in Group XIV] To ensure that clamping means for aircraft controls, that are used to prevent the control surfaces flapping in the wind when the aircraft is parked, are disengaged before a " take-off," obstructing means for the pilot's seat are provided and these can only be put in the unobstructing position after having been unlocked by a key attached to the clamping means which must thus be brought to the seat for this purpose. Control rods 13 are arranged to be clamped by a removable member 16. The pilot's seat 10 has an arm 17 that is hinged at 19 to a fixed bracket 20 in which slides a locking-bolt 24 adapted to enter holes 26, 27 in a plate 21 which, with a bottom plate 23 which limits the downward movement of the bolt, is secured to the arm 17. The plate 23 is stepped as shown, so that the downward movement of the bolt is greater for the holes 26 that correspond to the obstructing position of the arm 17 than for the holes 27 that correspond with the unobstructing position. A key 29 for operating the bolt is attached by a chain 31 to the member 16. Assuming the arm 17 to be in the obstructing position shown, it is thus necessary for the member 16 with the key to be carried to the chair to permit insertion of the key in a slot in the bracket 20 with the ward 291 of the key engaging between shoulders 25 on the bolt. When after raising the bolt the arm 12 is turned to the unobstructing position, the bolt enters the hole 27, but as it cannot move downwards sufficiently to register the ward 291 with the slot, the key cannot be withdrawn to enable the member 16 to be carried back to the rods 13. A receptacle 32 is provided for the member 16 while the arm is in the unobstructing position.

Title: Improvements in arc-rupturing devices for electric switches
IPC: H01H33/985
Filed: 1937-03-24
Abstract: 492,721. Fluid - blast switches. LANGE, E. March 24, 1937, No. 8666. Addition to 455,115. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 28, 1937.] [Class 38 (v)] The invention described in the parent Specification is modified in order that the arc at the outlet should not be produced until adequate pressure is developed to rupture it, by providing a switchoperating lever which acts directly on the movable contact of the principal break disposed in the confined space and co-operates with means for causing the movable contact of the other break to open the circuit at the outlet after the first break has been formed. The fixed contact 16 has an outlet closed by valve 17 and co-operates with a contact 15 mounted on the bell 12 which is slidable on guides 9 in the insulating chamber 11. Contact 15 is integral with socket 14 with which the rod contact 13 co-operates. In order to produce the arc in the bell before contacts 15, 16 separate, 13 is extended downwards and provided with a pin 21 engaging in a slot 22 for direct operation by lever 20, this lever having a pin 37 engaging a cam slot in an arm 35 pivoted at 36. The forked free end of 35 is engaged by a pin on a bell-crank lever 30, which is pivoted at 42 and has a pin-and-slot connection with levers 26 pivoted to the bell at 27. When 20 is rotated, contact 13 is lowered at once to draw an arc, but owing to the part 38 of the cam slot being concentric, no movement of lever 30 and the bell occurs. When pin 37 enters part 39 of the slot, the pressure developed by the arc in the bell is adequate to open the valve, and accordingly slot-part 39 is so made as to tilt arm 35 outwards, so drawing down the bell and opening contacts 15, 16. Part 40 of the slot being also concentric, no further deflection of arm 35 occurs while the rod 13 moves on downwards. When 13 clears partition 10, the fluid escapes from apertures 43 and valve 17 closes. The fluid may be liquid, air, or other gas and in the latter case may be maintained under pressure.

Abstract: 1298302 Photographic equidensity images AGFA - GEVAERT A G 5 April 1971 8666/71 Addition to 1248071 Heading G2C Photographic equidensity images by exposing a material comprising two silver halide emulsions (i) a first emulsion containing 65-90% by weight based on total silver halide of a first silver halide, and (ii) a second emulsion containing 10-35% by weight of a second silver halide, the second silver halide being faster but less soluble in the developer bath used than the first silver halide, developing the exposed material in a developer containing a silver halide solvent so that the first emulsion is physically developed to give a positive silver image and chemically developed to give a negative silver image and the second emulsion is chemically developed to give a negative silver image, and then fixing the material. The first silver halide should be spontaneously developable in developer of low bromide ion content or development nuclei should be present, and the developer should contain little or no bromide ion. On development bromide ion from the second (faster) silver halide inhibits physical development of the first silver halide. The two emulsions may be in separate layers or may be mixed in the same layer. The emulsions may be spectrally sensitized to be each sensitive to different parts of the spectrum when the use of differently coloured filters enables various equidensity characteristics to be selected.

[Class 98 (ii).] In order to prevent collodion plates becoming horny when dry, the plates, coated with a silver halide collodion emulsion, are bathed with a solution containing a known softening agent, a dyestuff of the quinoline group or ethyl violet and a soluble silver salt of an inorganic acid; or with a solution containing a softening agent, a silver salt of a dyestuff of the phthalein group and possibly also a quinoline dyestuff. If the plate has previously been dyed with a quinoline or phthalein dyestuff it may be bathed with a solution containing a softening agent and an alkaline silver solution. In examples: (1) a collodion silver halide plate is bathed with a solution containing glycerine, the silver salt of eosine and a iarge excess of alkali: (2) a collodion silver halide plate, which may have been previously dyed with a quinoline dye, is bathed with a solution containing glycerine, a strongly alkaline solution of the silver salt of eosine and an alcoholic solution of a quinoline dye, e.g. pinacyanol, or of ethyl violet: (3) a collodion silver halide emulsion dyed with fluorescein, erythrosine or eosine, or with a quinoline dye, or with two of these dyestuffs, is treated with a strongly alkaline solution of silver nitrate. A protective colloid, e.g. gelatine, albumen, albuminates or gums, may be added to the sensitizing solution or to the silver solution to prevent clouding of the plate during drying. Sugar is also mentioned as a softening agent for collodion.

Abstract: 1,212,741. Antibiotic B-2847. TAKEDA YAKUHI KOGYO K.K. 23 Feb., 1968 [25 Feb., 1967; 9 Sept., 1967], No. 8879/68. Heading C2A. The antibacterial antibiotic B-2847 and its components B-2847Y and B-2847R are produced by culturing Streptomyces tolypophorus ATCC 21177 or a B-2847-producing mutant thereof, in a medium containing assimilable sources of carbon and nitrogen and inorganic salts under aerobic conditions. The antibiotic is recovered from the clarified broth or separated mycelium. The clarified broth is washed with n-hexane, adjusted to pH 2 to 8 and extracted with a water-immiscible solvent such as ethyl acetate. The extract is washed with aqueous phosphate buffer of pH 8À0 and then with water. After concentration, the crude antibiotic, as B-2847Y, is precipitated by the addition of n-hexane. Further purification is by chromatography on silica gel using benzene-ethyl acetate (1:1), adsorption on activated C and recrystallization from n-hexane-ethyl acetate. The separated mycelium may be extracted with acetone-water (3: 1), filtered, concentrated, adjusted to pH 3À5, extracted with ethyl acetate and crude antibiotic precipitated by the addition of n-hexane. B-2847R is the reduced form of B2847Y and is recovered in the pure form when any of the above isolation and purification steps are carried out in the presence of L-ascorbic acid. The antibiotic components are easily soluble in CH 3 OH, C 2 H 5 OH, n-butanol, acetone, chloroform, ethyl acetate or benzene; insoluble in water, petroleum ether or n-hexane. Pharmaceutical preparations for topical use, e.g. ointments, comprise the antibiotic B-2847Y or B-2847R. Solutions of the antibiotics may be used as a general disinfectant.
